对100侧腹股沟区进行了解剖观察。腹股沟韧带平均长12cm,宽0.6cm;腹股沟管平均长4.7cm;腹股沟镰有四种类型:(1)联合腱型占66%;(2)肌一腱膜混合型占15%;(3)结合肌型占14%;(4)腹横肌腱膜型占5%。有10%的腹壁下动脉行程异常,其中 S 形(高位弯曲)和 L 形(低位弯曲)各5例。腹股沟后壁可分为两层紧贴的筋膜层,并成一个“梨状窝”,其平均纵径为2.9cm,横径1.4cm。加强和重建后壁,现已被认为是腹股沟疝手术成败的关键。
One hundred lateral groin areas were dissected. The inguinal ligament has an average length of 12 cm and a width of 0.6 cm. The average length of the inguinal canal is 4.7 cm. There are four types of inguinal falx: (1) the combined tendon type accounts for 66%; (2) the muscular- Combined with muscle type accounted for 14%; (4) Transverse abdominal fascia type accounted for 5%. 10% of the inferior abdominal artery anomalies, including S-shaped (high bending) and L-shaped (low bending) in 5 cases. Inguinal wall can be divided into two layers close to the fascia, and into a “pear-shaped nest,” the average longitudinal diameter of 2.9cm, diameter 1.4cm. Strengthening and reconstruction of the posterior wall, has now been considered the key to the success or failure of inguinal hernia surgery.
